Hey, it's the notorious JLJ.
It's strange how many people portray her (older self) as a sex object, and little more. I never thought she was that pretty really. So what's my take on her?
I've seen a few takes on her in which she actually improves herself after she split up with Bart. As much as I like that idea it's my job to idiotically fly in the face of as many things as possible
. After being exposed as a theif in this continuity, she actually gets much, much worse. She pretends to be a changed person but... she is but not in the right way.
Her facade appears to be more effective than ever but she's quick to shed it towards certain people. She's become foul tempered, sometimes foul mouthed and not to far away from murderous, she constantly attempts to make people, especially Lisa and Maggie as miserable as possible with a clique of shallow Waverly hills morons at her disposal.
Fortunately she fails at everything, so often that the Simpson kids consider her to be no more than a sad, pathetic joke (not far from the thruth) which explains why she's shifting her malice on Sherri and Terri.
She'll probably get better later i life but it'll take some drastic humiliation to set her on the right track, or not.
